Abel Ferrara’s 1981 rape-revenge movie Ms.45 is all too often forgotten by film fans. Maybe it’s because, in the UK, it never made it onto the Department of Public Prosecution’s final banned list in the early 80s, like Ferrara’s iconic video nasty Driller Killer (1979). Or maybe it’s because, for exploitation fans, it’s just not as grisly as Meir Zarchi’s I Spit on Your Grave (1978). What is certain is that Joe Delia’s score has never received any real appreciation outside the context of the film because, up until now, it has never been released.

Ms. 45 is the New York tale of Thana (the late Zoë Lund), a mute seamstress who survives not one rape attack, but two: first in the street, and then, when she gets home, a burglar, waiting in her apartment, repeats the ordeal. What follows is a shocking one-woman rampage against all male chauvinists.

Joe Delia started out in music in the late 60s, touring in backing bands for the likes of Stevie Wonder and The Isley Brothers. In the 70s he studied composition, and got his big break with Ferrara’s first feature, Nine Lives of a Wet Pussy (1976). His career in film and TV now spans almost four decades.

The score of Ms.45 was his third feature-length effort. He had the tough job of jamming out the real sounds of New York, as well as making up for the glaring silence of our mute anti-heroine. For example, down-tuned guitars cling to a racing post-punk rhythm, intensifying the horror as Thana is dragged from the street in the first attack. Whereas, when the burglar points his gun at her, the shrill of a saxophone, like a crazed seagull, pleads: not again, because she can’t. When her transformation into Ms. 45 is complete, Delia subverts this saxophone motif to signify Thana’s rebirth as a woman of vengeance. Her full red lips take centre stage as the music demands you know she’ll no longer be a victim. These dramatic, broad musical tones are complemented by gentler, stripped-down piano compositions.

Everyone who knows this movie knows ‘Dance Party’, and its Liquid Liquid/ESG-type disco-punk groove. On screen a band performs it at a fancy dress party as Thana – in a sexy nun’s habit – bides her time before her final, fatal act of vengeance. [SPOILER] For this climax Delia switches, on the first gun shot, to the haunting Gregorian sounds of ‘Voices’ as Thana shoots every man she finds in her cross hairs at the party – only to be halted when one of her fashionista colleagues (literally) stabs her in the back.

Delia recorded four other tracks for Ms. 45, but they only featured as snippets in the final film. He doesn’t consider these part of the score so they do not appear on the Death Waltz record. However, they are included as digital extras when you buy it, together with two elements tracks – 25 and 45 minutes long – thrown in for good measure.
